 4-fided pyramids whofe angles are often truncated : when 

 heated it whitens, and burns in the open air without odour, 

 and without being fenfibly charred, leaving a white refi- 

 duum which at firft has no tafte, but at length leaves an acid 

 impreflion on the tongue: fradure conchoidal or indeter- 

 minate : fpeciiic gravity i ,666*
